PRINTING-PRESS APPLIANCE.

Application filed (I ctober 29, 1913.

It; all whom it may concern:

Be it known that 1, JAMES E. Donn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga, State of ()hio, have invented a new and useful Tmprovement in Printing-Press Appliances, of which the following is a specification, the principle of the invention being herein explained, and the best mode in wh ch I have contemplated applying the principle, so as to distinguish it from other inventions.

This invention has reference to an appliance intended for attachment to that style of printing press which includes a platen and a disk upon which inking rollers are lntended to reciprocate. The features of the invention are associated specifically with the track and the disk according as they prescribe the positioning of one with respect to the other.

Until recently, in so far ,as l have become cognizant, no support, such as a track, has been provided for the saddles wh le passing over the disk to the end of relieving the soft composition rolls of undue pressure. Attempts to do this have been unsat1sfactory principally because the oining of such supports was not thoroughly efiected, it being accomplished as economically as posslble in connection with the free extremities of the earlier type of track which adjoined the platen but not the inking d1sk. My lnvention provides a suitably massive bracket either integral or in precise and durable connection with the track-formmg portion of the frame which in the standard type borders only the platen. As such, my bracket forms a nice continuation of the track on opposite sides of the disk and itself supports on its upper end the required fountaln.

It is furthermore awkward at present to effect the cleaning of the rollers preparatory to the application either of a difierent or merely fresh supply of color thereto, for the reason that they must be brought over the apex of the track or in the position where neither the platen nor disk is directly underneath. My invention provides ad ust1ng means for the separation of the d1sk and the laterally adjacent tracleinto more remote planes whereby the wlpmg or cleaning of the rollers may take place even while superposed with reference to the d1sk.

The inventive conception is embodied in means which are hereinafter explained and variously combined in the claim, while the annexed drawing and particular descriptlon thereof together set forth in detail several Specification of Letters Patent.

certain means constituting my invention, the disclosed means however, being but some of various mechanical forms in which the principle of my invention may be applied.

Directing attention to the drawing in which 2-- Figure I is a side elevation of an appliance embodying my invention.

Fig. 11 is a rear elevation of the same. Fig. III is an elevation of a modification respect to one feature.

Fig. TV is a section on line TV IV looking in the direction of the arrows.

The construction constituting my appliance is wholly adapted for attachment to the upper portion of the printing press, hence only so much of the latter is represented as will indicate the conjunctive purpose of the invention. The supporting frame 1 is provided on both of two opposite sides with a pair of substantially horizontal flat surfaces or pads corresponding pairs being designated as 2 and 3 respectively. The frame is furthermore fashioned with forward trackforming edges which are bent obliquely upward at at. The portion of the frame 1 adjacent the track edges 4 are formed with rightangular recesses comprising the flat surfaces 5 which are inclined obliquely upward and the shorter transverse surfaces 6 which terminate in the surface of the tracks 1. A carrier 7 is pivotally mounted to the frame at 8 and itself carries the two rods 9 to the eX- tremities of which the saddles 10 are pivotally connected. These latter include among other things the usual pair of composition inking rolls carrying rollers 11 which are intended to travel upon the track-forming edges of the frame. A more detailed de* scription of the carrier and saddle mechanism need not be supplied since no invention is claimed as associated therewith.

A support 12 of approximately invert-ed U shape includes a pair of divergent extremities 13 adapted to lie seated upon the flat surfaces 2 as best seen in Fig. H. An interjacent portion 14 of the support 12 is provided at its own middle with an upwardly projecting boss 15 of circular crosssection having a bore 16 extending therethrough. The upper annular surface of the boss 15 is formed with four equispaced cams 17. The interjacent portion 1% is furthermore formed with an arched arm 18 having a curved slot 19 which should be an arc of a circle. The inking disk 20 here employed is provided underneath and centrally with a 45 continuation of the tracks.

boss 21 which is likewise of circular cross 23 extends through the opening 19 and into a suitably screw-threaded opening in the under surface of the disk 20. agency of this screw, which when loosened may he slid along the slot 19, the inking disk 20 may be raised or lowered at will and furthermore fixed in various positions relative to the support 12 and incidentally to that plane of travel of the rollers 11 which is prescribed at the uppermost point of the edges 4.

A pair of brackets 24 are each formed below with the inwardly extending surface 25 which are adapted to be superimposed 'upon the extremities 13 of the support 12. The upper ends 26 of these brackets extend rearwardly to a point beyond and above the uppermost edge of the inking disk 20 and there together support the needed fountain through the medium of fasteners 27 extending therethrough. Each of the brackets 24 is fashioned with another fiat under surface or pad 28 slightly elevated and to the fore with respect to the surfaces 25. The surfaces 28 are designed to simultaneously rest upon the surfaces 3 of the frame. The upper forward edges of the brackets 24 are also of right angular construction to include surfaces 29 and 30 adapted to form a close mechanical fit with the surfaces 5 and 6 respectively as clearly seen in Fig. I. The upward extent of the surfaces 30 corresponds throughout with that of the surfaces 6 whereby the elongated upper edge 31 of the brackets may lie Qopies of this patent, may be obtainedfor flush with the top, surface of the edges 4 and thereby establish a smooth and very durable The brackets 24 are screwed to the frame through the medium of bolts 32 two of which are shown to also extend through the extremities 13 to simultaneously fix these at such points. The arrangement is necessarily such that the upper surface of the inking disk 20 normally lies in substantially the same inclined plane as the plane of the inclined edges 31.

It will be understood therefore that the construction of the support 12 and the brackets 24 permit of either raising or lowering the inking disk 20 with respect to the rollers 11 when they chance to be at rest thereabove, and thus another feature of practical convenience is attained.

The modification with which Figs. III and IV have to do, consists in an alternative The under surface of the boss Through the mode of separating the saddles from the ink- I V I ing disk. Such separation is-again the raising or lowering of one with respect to the other. The preferred form illustrates mechanism adapted to lower the disk. According V to this modification means for elevating the saddles with respect to the disk is provided in order that the rollers carried by the saddles may be rotated without friction and enable the ink to be more readily wiped from their peripheries. In this modified .form the upper inclined edges of the bers are provided near their upper ends with depending ears 38 and adJacent thereto the brackets 24 have elongated and upwardly inclined slots 39 substantially parallel with the surfaces 34. Thumbs'crews 40 extend through the slots 39 and suitable openings in the ears 38 whereby the upper edges 37 may be fixed so as to either lie flush with the edges 4 or rest in an elevated position. The saddles are also in the latter event necessarily elevated and the rollers 11 thereon in consequence removed from contact with the inking disk as wished.

My invention being thus described with suiiicient thoroughness, what I desire to se-' cure by Letters Patent and therefore claim specifically, is V r r A printing press appliance comprising in combination a frame formed above with tracks, a bracket structure supported thereon and having continuing track surfaces, a saddle having inking rolls adapted to be supported upon said continuing track surfaces, a support below said bracket structure, an inking disk adjustably mounted upon said support so as to permit of raising and lowering with respect thereto and means for fixing posed to form smooth continuations of the upper edges 4. These track forming mem-' said disk in various positions of rest with 1 JAMES E. DOYLE. I
